Tāufaʻāhau Tupou IV

Who is Tāufaʻāhau Tupou IV?

Tāufaʻāhau Tupou IV was King of Tonga from 1965 until his death in 2006, and the son of Queen Sālote Tupou III. Educated at Newington College in Australia and later at the University of Sydney, where he earned both a bachelor's degree and a law degree, he was appointed Minister of Education in 1943 and Minister of Health in 1944 by his mother, before serving as Prime Minister of Tonga from 1949 until his coronation in 1965. His nearly forty-one year reign was marked by sweeping efforts to modernize the kingdom, expanding education, healthcare, and infrastructure while working to maintain Tonga's cultural heritage and its status as the only Pacific nation never colonized. In the 1990s he undertook a widely publicized personal fitness campaign, losing roughly a third of his body weight, having previously been the tallest and heaviest Tongan monarch on record. His later reign also saw the rise of Tonga's pro-democracy movement, as growing calls for constitutional reform challenged the traditional authority of the monarchy and nobility, a debate that continued after his death in 2006 at age 88.
